IfcElectricApplianceType

Definition from IAI: An IfcElectricApplianceType defines a particular type of common electrical appliance found in a typical AEC/FM facility. Electrical Appliances generally consist of electrical devices that are not a fixed part of the building but instead can be moved from one space to another and are powered with electricity.

HISTORY: New entity in IFC R1.0. Renamed from IfcElectricalFixture in IFC 2x. Renamed as IfcElectricalApplianceType in IFC 2x2.
